Study on cultivation mode of hot pepper in dry land
摘要
Abstract
In dry conditions, a two-factor randomized block design was adopted [Factor A is cultivation method, set ting two levels of Direct seeding (Al) and Bowl-real transplanting (A2); Factor B is film mulching mode, setting three levels of Full plastic film mulching on double ridges and planting in catchment furrows (Bl), Plastic film mulching on ridge and planting in film-side (B2) , Flat planting of full ground plastic film mulching (B3)] to study the effects of different cultivation modes on hot pepper yield, soil moisture content and soil temperature in dry land. The results showed that, compared with Al, the pepper flowering date in A2 was 16 d earlier, red fruit harvest date was lid earlier, while the fresh red pepper yield was 13.51 % higher, and the total fresh pepper yield was 4.43% higher. The total fresh pepper yield and red pepper yield in BI + A2 were the highest, while the yield of fresh green pepper in Bl + A2 was the highest. Bl and B2 can effectively collect rainwater; B3 had the best effect in keeping moisture, and Bl followed. Before fruit setting, with the weather warming, soil temperature rose, different plastic film mulching modes had different effect on soil temperature, B2 was the fastest for increasing soil temperature, but was the last for maitaining temperature, while Bl had the best effect on maitaining temperature. In the red fruit harvest, as the ground was covered by plants, the soil temperature decreased, the soil temperature in different mulching modes got similar. Therefore, adoption of Bl ccould obtain the best effect of rainfall-collection and soil moisture preservation, as well as heat preservation. Bl + A2 also had best effect in plant height, plant width, number of fruit per plant and total red fruit, red pepper yield and total fresh pepper yield, so as the economic benefit. So it is recommended in hot pepper cultivation in dry land.关键词
